PASTEURIZING-MACHINE.

Specification of Letters Yatent.

Patented June 4,1912.

Application filed May 16, 1911. Serial No. 627,439.

To all whom may concern:

lie it known that l, (ins'rav A. FISCHER, a citizen of the United States, resident of Cleveland, county ofCuyahoga, and State of Uliio, have invented a new and useful Im provenient in Pasteurizing-Machines, of Whit-u the following is a specification, the principle of the invention being herein explained and the best mode in which I have 'contem )lated a )l in that )rinci do so as to distinguish itfrom other inventions.

'lhis inventiiin has reference to a pasteuri /iing machine, and more particularly to the operative relation of certain specific elements of construction.

'ihe object is to provide a machine of this character whicu while simple and economical in manufacture, will be more etiicient.

The said invention consists of means which are hereinafter fully described and particularly set forth in the claims.

'lhe annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various nnchanical forms in which the principlc of my invention may be employed.

Referring to the drawing :Figure 1. is a vertical section of a pasteurizing'machine embodying my invention. Fig.2 an clevation of one inventive feature.

The machine con'ipriscs, in the disclosed form a circular" pan ii. having the sides a. Rowing upon the base or" this pan and precislv covering the same so as to form a trough a: in conjunctioi'i with the sides a is a dome 'fflllllQtl at its apex with an axial bearing 7). This trough is 'n-ovided with an outlet (1", as sl'iown. The dome, otherwise closethis provided with a steam inlet pipe 6' and steam outletpipe L these being adapted to effectthe heating of the dome in the customary manner.

A skirt covers the dome B and, as roprcscnted in l, gravitationally rests upon the edges of the sides a. The skirt is of suilicient dimensions to insure its being spaced a necessary distance from the dome. Furtl'ierniore, the shirt in accordance with my invention and as constituting one feature thereof, should be stationary. It is provided at the top with the usual funnelshaped receiving inlet a and sieve across its constricted connecting portion. The lower annular edge of the skirt is fashioned as a flange .2 to preclude dust and sediment of various kinds from settling in the trough or upon the contents therein. A depending annular flange 0* is also provided interiorly of the edge of the trough, to insure the guidance and eventual dripping of any fluid coming in contact with the skirt into the trough.

A suitable driving-shaft D projects up through the bearing b of the dome to a point above the top thereof, and is provided at that point with a triangular extremity d. Mounted upon this extremity through the medium of a correspondingtriangular open ing 6, so as to rotate with it, is a rotary Wiper E. This Wiper is formed, as clearly seen in F 2, with a plurality, in the present instance by Way of exemplification, three depending and preferably rigid fingers e, overlying the upper surface of the dome B. The under surface a of each of these fingers substantially conforms in curvature to the upper surface of the dome. The fingers e are also substantially similar in shape, and are equally spaced each with reference to the other, and hence necessarily diverge downwardly. They moreover extend to a point near the bottom of the trough, as clearly seen in Fig-1. The under surface of the iping fingers 6 may be in light contact with the surface of the dome, though. preferably immediately adjacent and not actually contiguous thereto, as clearly appearing in Fig. 1. The thickness, or that dimension of the Wiping fingers c which is substantially perpendicular to the surface of the dome at that point, such that a sufficientfree space is afforded between their upper surfaces and the inner surface of the skirt.

In operation, assuming the dome properly heated and the rotary Wiper to have been started, the milk or other liquid which is to be subjected to the pasteurizing process is poured into the receiving inlet 0" and immediately after passing through the sieve is Whipped about upon the upper surface of the dome. The wiping fingers e serve in addition to prevent any tendency on the a part of certain fluids to thicken and accordingly insure a continuous flow into the trough and out of theoutlet a It should, be especially noted that during the opera tion of the machine, the skirt C constantly remains stationary and furthermore entirely covering the trough, as it does by inclosing the upper edge,'positively precludes any objectionable matter reaching the fluid under treatment. Then, too, the wiping means is positive and absolutely independent of both the dome and skirt by reason of which it is calculated to attain the consummate efficiency desired.

Having fully described my invention, what I claim and desire to secure byLetters Patent is:

1a A pasteurizing machine comprising the combination of a chamber having an inclined upper surface, means for heating said chamber and'positioned beneath said surface, a removable skirt conforming to and substantially inclosing said surface, and an interposed wiper having a finger conforming to such upper surface and independently movable relative to the chamber and skirt.

2. A pasteurizing machine comprising the combination of a dome, means for heating the same, a trough surrounding the lower portion of said dome, a removable skirt covermg said dome and gravitationally resting upon said trough, and a Wiper having divergent fingers interposed between and movable relatively to sald dome and skirt.

3. A pasteurizing machine comprising the .outlet, a removable skirt spaced from said dome and resting upon said trough, said skirt being provlded above with a receiving inlet, a driving shaft extending to the 7 top of said dome, and a rotary wiper secured to saidshaft and including a plurality of downwardly divergent fingers interposed between said dome and skirt.

4. A pasteurizing machine comprising the combination of a stationary dome, means for heating the same, and positioned entirely Within said dome, a trough surrounding the lower portion of said dome and provided with an outlet, a driving shaft projecting upthrough said dome, a rotary wiper se cured to said shaft and overlying said dome, and a removable skirt covering said wiper and trough, and provided above with a single receiving inlet.

Signed by me, this 15th day of May, 1911.
